This invention relates to a coupling or tting for a pipe or tube line,invention being to provide a iltting which will prevent the parts of theline being damaged by vibrations while insuring a iluid tight connectionbetween the parts.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafter fully described, -illustrated in the accompanying drawingand specifically pointed out in' the appended claim.

In describing the invention in detail. reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding and in parts throughout the -several views, which:-

Figure l is a longitudinal. sectional view showing the invention in usewith a double unit.

Figure 2 is a longitudinal sectional view through one oi the couplingsor fittings.' v

As shown in this drawing the improved fitting or coupling consists of asleeve A composed oi an inner .tubular part I of plastic compositionmaterial and the metal tubular part 2 which surrounds the part I but atone end o! the part I is an outward flange 3 against which one end ofthe member 2 abuts as shown. The inner member l has its other end.enlarged and iiaring internally as shown at I. the exterior part of theenlargement iitting in an-enlarged' end 2' -of the vmember 2. thisenlargement forming a shoulder l at the inner end of the enlargement. y

Thus when the device is used with a coupling. asshowninlligure 1the'iiared part! oi the inner member I Awill engage the daring end ofthe tube which engages the tapered end to! the bodymemberloithecowlinsorunionandthe dangeoi'thenutl oftheunionwlllenmthe thegeneral obiect of the shoulder I and thus the device will to the bodylmember 1 of and the ilange o! the nut gage the shoulder i and connectedto into the union will b'e connected the coupling or union l oi' theunion will enthus the device will be the body member of the union in a siluid tight manner receiving the part of and the composition memberthepipe or tube extending have a iluid tight dt thereon and this compositonmember engaging the end of said tube and parts of vibrations and preventsuch vibrations trom damaging the line by causing crystallization atparts of the line.

It is thought the union 1 will absorb l0 *from the foregoingdescriptionV that the advantages and novel features ot the 15 inventionwill be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement thatsuch changes appended claim.

Having described as new is:-

of the several parts provided tall withinthe scope ofthe zo" theinvention what iskclaimed- A ntting for preventing vibration in a pipeor tube line comprising an elongated .sleeve-like 25 member, includingtion inner part, ing `an exteriorv adjacent end of the a metal part anda composlsaid composition inner part haviiange at one end abutting themetal part and the other end of said inner part being exteriorlyenlarged and 30 said end being internally iiared to iit the outwardlyiiared end of a tube on which the member is placed. the metal vlai-gedto receive part having one end enthe enlarged end of the inner part andsaid enlarged endA of the metal part forming a shoulder ment by amember'v another member.
